[Tigers] Valve cover clearance??

[CoolVT at aol.com]

Can anyone tell me what the clearance is from the top of the valve  cover to 
the underside of the cowling?  My engine has roller rockers and  original 
style low covers won't fit over rockers and typical cast covers also  will not 
fit.  Seems as if I am going to have to go with something taller  and I know 
fitment is an issue.  Since I won't have to be removing valve  covers for 
adjustments, what height can I get away with in a cover that will fit  under the 
cowling?
Any ideas on brand names that will work in this situation or should  I be 
looking at cover spacers?
